V-COIL Inserting Tool M 33 x 2.0, 1/2 inch square drive

A wire thread insert installation tool in size M 33 x 2.0, this V-COIL inserting tool drives coiled wire inserts into a prepared tapped hole. The working end is a threaded mandrel. The V-COIL wire thread insert is screwed onto that mandrel and guided down into the hole. At the shank end sits a 1/2 inch square drive.

The square connector accepts ratchets, hand wrenches and square-drive power tools. VÖLKEL lists the tool in the V-COIL range and builds it to Works Standard. The thread system is metric, with a size range limited to M 33 x 2.0. Each unit is supplied as one piece. Installation follows the usual V-COIL repair order: drill, tap, then set the insert. Keep the tap and the insert in the same M 33 x 2.0 size as the mandrel.

Wire thread insert installation tool M 33 x 2.0 with 1/2 inch square drive

Repairing a stripped M 33 x 2.0 thread calls for three matched items: a tap, a wire thread insert and a mandrel that turns the insert home. This model covers the third step. The mandrel thread mirrors the insert geometry, so the coil stays supported while it enters the hole. The drive end keeps torque input in line with the mandrel axis.

Construction and drive connection

The body combines a threaded mandrel with a plain drive shank. The insert winds onto the mandrel before installation, then unwinds into the tapped hole as the tool rotates. The 1/2 inch square drive lets you choose a manual ratchet for controlled feed, or a powered square drive for repeat work. One tool covers a single thread size only.

• Tool form: threaded mandrel with drive shank
• Drive connector: 1/2 inch square drive
• Operated with a wrench, ratchet or power tool
• Thread system: metric (M)
• Thread designation: M 33 x 2.0

Match the mandrel to the insert length and thread size before starting. A hole that has been drilled and tapped to the M 33 x 2.0 V-COIL specification is the working condition assumed here. Feed the insert slowly and keep the tool square to the hole axis. Uneven feed can distort the first coils and leave the insert standing above the face.

Thread data and scope of supply

All catalog data points to one fixed configuration. The size range is stated as M 33 x 2.0, with no additional sizes on this item line. The reference standard is Works Standard. Package quantity is one piece, so multi-size workshops build up a set by ordering separate mandrels for each thread they service.

• Product type: V-COIL inserting tool
• Size range: M 33 x 2.0
• Standard: Works Standard
• Package quantity: 1 piece

Because the tool is size-specific, record the thread size on the storage position. That keeps the mandrel, the tap and the insert box together during a repair. For other metric sizes, request the matching inserting tool from the same V-COIL range rather than forcing an insert onto a mandrel of a different pitch.

Common applications

Thread repair in large aluminium and cast housings is the usual use case for an M 33 x 2.0 mandrel. Typical work includes gearbox and engine casings, hydraulic blocks, machine bases and heavy fixtures. Wire thread inserts also reinforce new threads in soft materials that see frequent bolt removal. The 1/2 inch drive suits maintenance benches, mobile repair kits and production lines where a powered square drive speeds up repeat installation.

Ordering notes

Order one mandrel per thread size you plan to service. Confirm the insert type and length used on the joint, then confirm the tapping tool size. All three items must state M 33 x 2.0. Check that your ratchet or power tool carries a 1/2 inch square output before delivery.
